r 4 Y Claims.

Another very important object of the invention is to provide, in a hand tool comprising a plurality-of toothed discs or, cutters engageable with the wheel, novel means for adjusting or feeding said cutters relative to said wheel.

Other objects of the invention are to provide a grinding wheel tool of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of thefollowing specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan View of a grinding wheel tool constructed in accordance with the present invention.

Figure 2 is a view in side elevation thereof. Figure 3 is an end elevational View.

i is a cross sectional View, taken sub stantiaily on. the line =lt of Fig. 2.

Referring now to the drawing in detail, it will seen that the embodiment of the invention which has been illustrated comprises a handle l of suitable material. Extending longitudinally into handle 5 from the forward end thereof.

is a slot 2 providing spaced, parallelbifurcations Extending longitudinally through the handle 8 is a bore which communicates with the slot 2. Adjacent the bifurcations 3, the handle I is further provided with a transversely extending slot or opening 5 which communicates with the bore t.

.ne free end portions of the bifurcations 3 have formed integrally therewith a pair of lugs or ears 5 the piu'pose of which will be presently set forth. Extending between the free end portions.

of the bifurcations 3 is a removable pin "l. A cotter pin is retains the pin '8 in position. The numeral 3 designates a plurality of toothed cutter discs which are mounted on the pin l between the bifurcations 3. Spacers ill (see Fig.3) separate pairs of the cutters 9.

Mounted for sliding adjustment between the moved into contact with saidwheel.

bifurcations 3 is a combination stop and guard H of suitable metal which is of substantially the shape shown to advantage in Fig. 2 of the drawing. Referring now to Fig. 4 of the drawing, it will be observed that the stop I! has formed in its side edges notches or recesses I? which slidably accommodate the bifurcations 3. Threadedly connected to the stop H is a rod it which eX- tends slidably into the bore 4 in the handle I. Threadedly mounted on the rod l3 and operable in the slot ,5 of the handle I is an adjusting nut M. It will be observed that the adjusting nut i4 is knurled to facilitate rotating same,

It is thought that the manner in which the tool is used will be readily apparent from a consideration of the foregoing. With the grinding wheel stationary, the ears 6 are placed on the usual rest of the frame of the grinding wheel and the adjacent end of the stop I! is held against the outside edge of said rest. Through the medium of the nut M, the stop H is then adjusted to permit the cutters 9 to be moved to the desired position closely adjacent the periphery of the grinding wheel. The grinding wheel is then rotatedand the stop II is again adjusted in a manner to permit the cutters 9 to be gradually The tool is then moved laterally back and forth across the v through the medium of the nut It.

:It is believed that the many advantages of a grinding wheel tool constructed in accordance 1 with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

l. A grinding wheel tool of the character described comprising a handle having alongitudinal bore therein andfurther having a transverse slot therein communicating with the bore, parallel bifurcations on-one end of the handle, a plurality of toothed cutting discs rotatably mounted between said. bifurcations, a stop slidably mounted between the'bifurcations, a rod secured to said stop and extending slid-ably into the bore of the handle, and a nut threadedly mounted on said rod and operable in the slotin the handle for adjusting the stop longitudinally between the bifurcations. v

2. A grinding wheel tool of the character described comprising a handle, bifurcations on one end of said handle, supporting ears integral with the free end portions of the bifurcations, said ears being engageable with a portion of the grinding machine, a plurality of cutter discs rotatably mounted between the bifurcations adjacent the ears, a stop slidably mounted between the bifurcations and engageable with the grinding machine, said stop being cooperable with the ears for positioning the cutter discs relative to the grinding wheel, and means for adjusting the stop longitudinally between the ears.

3. A grinding wheel tool of the character described comprising a handle, bifurcations on one end of said handle, supporting ears integral with the free end portions of the bifurcations, said ears being engageable with a portion of the grinding machine, a plurality of cutter discs rotatably mounted between the bifurcations adjacent the ears, a stop slidably mounted between the bifurcations and engageable with the grinding machine, said stop being cooperable with the ears for positioning the cutter discs relative to the grinding wheel, and means for adjusting the stop longitudinally between the ears, the handle having a bore extending longitudinally therethrough, said means including a rod threadedly connected to the stop and extending slidably into the bore, and an adjusting nut threadedlymounted on the rod in the handle for shifting said rod longitudinally.

4. A grinding wheel tool of the character described comprising a handle having a bore extending longitudinally therethrough, bifurcations on one end of said handle, a plurality of cutter discs rotatably mounted between the free end portions of said bifurcations, a substantially arcuate stop slidably mounted between the bifurcations, said stop having notches therein slidably accommodating the bifurcations for mounting said stop therebetween, a rod connected to the stop and extending slidably into the bore, the handle further having a transversely extending slot therein communicating with the bore, and a nut threadedly mounted on the rod and operable in the slot for adjusting the stop longitudinally between the bifurcations.
